A communication system of a motor vehicle is provided. The communication system includes a vehicle operating unit, a vehicle output unit, and an interface computer. The interface computer is connected to the vehicle operating unit and the vehicle output unit. The interface computer is implemented for the purpose of connecting a mobile terminal to the vehicle operating unit and the vehicle output unit such that information from the mobile terminal is displayable on the vehicle output unit and the mobile terminal is operable via the vehicle operating unit.

Connection of personal terminals to the communication system of a motor vehicle

A system of control devices communicate by way of one or more databuses of a motor vehicle. The system exhibits at least two diagnostics access points, by way of which the state of at least one of the control devices is diagnose&#x2dc; on the basis of a diagnostics request message; in particular, an error memory entry of a control device is requested by way of one of the diagnostics access points and is transmitted to the outside. A diagnostics request message, which is fed to the system by way of the first diagnostics access point, is recognized as such by an identification and forwarding system and is transmitted to a checking system. The checking system checks at least the authenticity of the diagnostics request messages and, optionally, forwards it to that control device, for which the diagnostics request message is intended.

System of control devices in a motor vehicle with protected diagnostics access points and method of using the system

In a method and apparatus for wireless transmission of messages between a vehicle-internal communication system and a vehicle-external central computer, the vehicle-internal communication system has acoustic output unit for the playback of a received message. In the vehicle-external central computer, the message, which is at first present in text form and is to be sent to the vehicle-internal communication system, is transformed into a phonetic transcription; the phonetic transcription, is then transmitted to the vehicle-internal communication system. In the vehicle internal communication system, the phonetic transcription is transformed to speech and is emitted via the acoustic output unit. Spoken messages from a vehicle occupant are recorded via an acoustic input unit, processed and transmitted to the central computer by reversal of the same process.
